I think Pete used Haskell because there are not many documents online on Haskell + Networking. Other options? You can do it in C, if you want to do it at low level or Python if you want to do it in fewer number of lines of code.

I am sorry, I think I misunderstood your question to why Pete used Haskell here. If your question is on why Pete is planning to use Haskell for Browserling, that's something only Pete can answer. And I am looking forward for that answer too.
